Available Bandwidth Estimation with Consideration of Broadband Convergence Networks

We propose new available bandwidth estimation method with considerations of broadband convergence network (BcN) where one can make use of quality guaranteed service. When customers are connected with each other through the best-effort network as well as BcN, it is hard to guarantee quality of service (QoS) over the best-effort network. Therefore, it is necessary to estimate accurate end-to-end available bandwidth to support end-to-end QoS. To address this issue, we use measurement algorithm, which are performed on the terminal equipment. In addition, the concept of the proportional share of link capacity is used for estimating available bandwidth.
